Description

Sudestada (Southeast blow) is the Argentinian name for a climatic phenomenon common to the Río de la Plata (an estuary formed by the combination of the Uruguay River and the Paraná River on the southeastern coastline of South America) and its surrounding region. The phenomenon consists of a sudden rotation of cold southern winds to the south-east. This change, while moderating the cold temperatures, loads the air masses with oceanic humidity, bringing heavy rain and rough seas in the coastal regions. Also, there is an increase in the intensity of the winds. The Sudestada can occur at any time of the year but is most likely to happen between July and October.
